Which expression has a sum of a 11/12? pls help. explain step by step in a way a 13 year old will understand.
a. 10/22+2/12
b. 5/4+3/4+3/4
c. 1/12+5/12+5/12
d. 5/6+6/6
c. they are all parts of 12, and when added together they equal 11/12. The formula to solve non proportionate fractions*or with different denominators* is to CROSS multiply and make the denominators equal, then add the numerators and SIMPLIFY.
*Cross multiply to make the denominator equal (you can google how to make fractions equal)
then add the numerators together
then simplify. PLEASE BE CONSIDERATE OF THE FORMULA AND DONT BE INTIMIDATED BY THE LOOK OF THE PROBLEM. They all have the same formula or method of solving. Good Luck!! I hope this helps.
The expression which has an equivalent sum of 11/12 is 1/12 + 5/12 + 5/12
check all options:
a. 10/22 + 2/12
The lowest common multiple of 22 and 12 is 264
= (120 + 44) / 264
= 164/264
divide through by 4
= 41 / 66
b. 5/4+3/4+3/4
The lowest common multiple 4 is 4
= (5+3+3) / 4
= 11/4
c. 1/12+5/12+5/12
The lowest common multiple of 12 is 12
= (1+5+5) / 12
= 11/12
d. 5/6+6/6
The lowest common multiple of 6 is 6
= (5+6) / 6
= 11/6
Therefore, the expression which has an equivalent sum of 11/12 is 1/12 + 5/12 + 5/12

The length of a rectangle is 3 inches. Enter an expression for the area of the rectangle if the width is w inches. Find the area of the rectangle when the width is 1, 2 , 3, and 26 inches
Answer:
An expression for the area of the rectangle if the width is w inches is
[tex]A =[/tex] 3w
when the width is 1 inch, Area = 3 square inches (in²)
when the width is 2 inches, Area = 6 square inches (in²)
when the width is 3 inches, Area = 9 square inches (in²)
when the width is 26 inches, Area = 78 square inches (in²)
Step-by-step explanation:
The area of a rectangle is given by
[tex]A = l[/tex] × [tex]w[/tex]
Where [tex]A[/tex] is the area of the rectangle
[tex]l[/tex] is the length of the rectangle
and [tex]w[/tex] is the width of the rectangle
From the question,
length, [tex]l[/tex] = 3 inches
width, [tex]w[/tex] = w inches
Hence, An expression for the area of the rectangle is
[tex]A =[/tex] 3 × w
[tex]A =[/tex] 3w
Now, to find the area of the rectangle when the width is 1, 2 , 3, and 26 inches
1. when the width is 1 inch (That is [tex]w[/tex] = 1 inch)
Then, [tex]A =[/tex] 3w
[tex]A =[/tex] 3 × 1
[tex]A =[/tex] 3 square inches (in²)
2. when the width is 2 inches (That is [tex]w[/tex] = 2 inches)
Then, [tex]A =[/tex] 3w
[tex]A =[/tex] 3 × 2
[tex]A =[/tex] 6 square inches (in²)
3. when the width is 3 inches (That is [tex]w[/tex] = 3 inches)
Then, [tex]A =[/tex] 3w
[tex]A =[/tex] 3 × 3
[tex]A =[/tex] 9 square inches (in²)
4. when the width is 26 inches (That is [tex]w[/tex] = 26 inches)
Then, [tex]A =[/tex] 3w
[tex]A =[/tex] 3 × 26
[tex]A =[/tex] 78 square inches (in²)
PV=nRT, solve for T
Answer:
[tex]\huge \boxed{T= \frac{P V}{n R} }[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
[tex]P \cdot V = n \cdot R \cdot T[/tex]
Dividing both sides by n · R:
[tex]\displaystyle \frac{P \cdot V}{n \cdot R} =T[/tex]
[tex]\rule[225]{225}{2}[/tex]
[tex]\huge\underline{\underline{\mathfrak{\red{A}\green{n}\pink{s}\orange{w}\blue{e}{r}}}}[/tex]
$$P \cdot V = n \cdot R \cdot T$$
Dividing both sides by n · R:
$$\displaystyle \frac{P \cdot V}{n \cdot R} =T$$

15 divided by 4 and 1/6
Answer:
15÷4÷1/6.
first of all change ÷ to ×.
which will be 15×1/4×6/1.
which will be 15×1/2×3.
which is 15×3=45/2.
the answer is 22.5 or 22 whole number 1/2.
15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.
To divide 15 by 4 and 1/6, we can convert the mixed number 4 and 1/6 into an improper fraction.
4 and 1/6 can be written as (4 x 6 + 1) / 6 = 25/6.
Now, we can divide 15 by 25/6:
15 ÷ (25/6) = 15 x (6/25)
= (15 x 6) / 25
= 90/25.
Now, the fraction 90/25 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:
= 90/25
= (90 ÷ 5) / (25 ÷ 5)
= 18/5.
Therefore, 15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.

Riangle ABC is isoscelesGJ bisects ∠FGH and is a perpendicular bisector of FH. Triangle F G H is cut by perpendicular bisector G J. Line segments F J and J H are congruent. Angle F G J and J G H are both 30 degrees. What is true of triangle FGH? It is a right triangle. It is an obtuse triangle. It has exactly 2 congruent sides. It has exactly 3 congruent sides.
Answer:
It has exactly 3 congruent sides.
Step-by-step explanation:
Since ∠FGJ = ∠JGH = 30° and GJ is a perpendicular bisector of FH, ∠GJF = 90°. So in ΔFGJ, ∠FGJ + ∠GJF + ∠GFJ = 180°.
So, 30° + 90° + ∠GFJ = 180°
120° + ∠GFJ = 180°
∠GFJ = 180° - 120°
∠GFJ = 60°
Also, since GJ is the perpendicular bisector of FH, ∠GJH = 90°. So in ΔJGH, ∠JGH + ∠GJH + ∠JHG = 180°.
So, 30° + 90° + ∠JHG = 180°
120° + ∠JHG = 180°
∠JHG = 180° - 120°
∠JHG = 60°
Since ∠FGH = ∠FGJ + ∠JGH = 30° + 30° = 60°
Since ∠FGH = ∠GFJ = ∠JHG = 60°
So, ΔFGJ is an equilateral triangle. Since all its angles are equal, so also, all its sides are equal. So, ΔFGJ is congruent by SSS and AAA so its 3 sides are congruent.
So exactly 3 sides are congruent in ΔFGJ.
Answer:
It has exactly 3 congruent sides

Find the coordinates of
the missing endpoint if M
is the midpoint of AB.
A(4, -8) and M(5,-2)
Answer:
B = (6, 4)
Step-by-step explanation:
You know that the midpoint is calculated as ...
M = (A +B)/2
Solving this for B, we find ...
2M = A + B
B = 2M - A
Filling in the coordinate values, we get ...
B = 2(5, -2) -(4, -8) = (2·5-4, 2(-2)+8)
B = (6, 4)
The episodes of a TV program are each 40 minutes long. Phill watches four episodes together. How long is he watching TV for ? Give your answer in hours and minutes.
Answer:
He is watching TV for 2 hours and 40 minutes.
Step-by-step explanation:
We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.
As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;
1 episode = 40 minutes
4 episodes = 4 [tex]\times[/tex] 40
= 160 minutes
So, the length of four episodes together is 160 minutes.
Now, we have to convert the time in hours and minutes;
As we know that 1 hour = 60 minutes
160 minutes = 120 minutes + 40 minutes
= 2 hours + 40 minutes
Hence, the length of four episodes together is 2 hours and 40 minutes.

Nancy put 80 acorns in her backyard. Then, she made a graph of how many acorns different types of squirrels
ate.
how many acorns were left after the squirrels ate?
Answer:
16
Step-by-step explanation:
If we take the partial image to be 1/2 of a full image, then there are a total of
5 1/2 + 2 + 6 + 2 1/2 = 16
acorn images on the graph. Each image represents 4 acorns, so a total of ...
4 × 16 = 64
acorns are represented on the graph. Since these are ones the squirrels ate, the remaining 80 -64 = 16 acorns were left uneaten.
